RESILIENT TIRE..v

To all whom t may concern: Y

Be Ait knownl that FIERINO DI CESARE, a citizen of thefUnited States, residing at N ew York city, in the county of New York and State of VNew York, has. invented certain new and useful Improvements in Resilient Tires, of which the following is a specification. 1

" rThis invention relates to resilient tires, particularly the novel construction vof the ,inner tube used tohold the ca'sing Vin an expanded position. l l

One of the primaryobjects of my invention is to providea resilient tire that em'- bodies all thev desirable features of a pneumatic tire,but eliminates the'undesirable features'o-f the pneumatic tire -such as blow-outs and punctures. 'Y l y A further object of my invention is to con-v struct a tire of-the abovestated character comprising aninner tube formed of a series of flexible strips and having means positioned at spaced intervals to connectV the strips and hold them in va shape approximate to that of the ordinary inner tube, and means positioned at spaced intervals within the inner tube formed by the exible strips to hold, said inner tube into bearing engagementwith the inner surface of the tirey casing.' A y A. still further object of my, inventlon is to.V provide means positioned between the inner tube and casing lto prevent injury to the casing causedbv the. frictional engagementof the flexible strips therewith.

f And a still further object of my invention Yis toprovide a resilienttire of the above statedv character, which is simple in constructionydurable, eiii'eient forV the purpose intended. and one that can be manufactured and placed on the market at a relativelvlo'w cost. V

These and like objects Aof myV invention will bebetter understood as the description proceeds and as is speciiically pointed out in Y the appended claims.

Referring to the accompanyingr drawingsV which forms a part of this specification and which clearly illustrates the construction of my resilient tire,

l a` slightly .claim is herein made, 2` the felly Aof a ywheel and 3 designates the fastening means asa whole for securing the casing and my im-` provedf tube` with the'felly of the wheel.` The fastening; means- 3 are of any well. knownv constructioni 'v l yMy improved inner tube comprises a series of flexible stripsy as` indicated by the numeral 4, which arecurved to conform tolthecurvature of the inner Vsurface ofthe casing 1'; The flexible strips 4 arelcurved longitudi nally around the inner surface'of the casingand are spaced apartfrom one another. The

flexible strips 4 are secured to a coveringlQ which is formed of any suitable material and the'strips i are secured thereto'in anyv suit-able manner. n e

Positioned within 'the tube formed by the:l flexible strips andthe coveringf12-v are a series of'expansion Vblocks designated by the numeral 6. These blocks are approximately circular in rcross section as in'dicatedr'in Fig. 2, which permits thelblock to conform to the shape of the inner tubeand the inner surface of the casing. In each of the blocksl 6 is providedan inverted V-slia'ped slot or re# cess 7 and extends thevfull length of the block and :has the upperportion or apex of the recess terminating at a point adjacent the upper surface of said block. rlhe wedge 8 is loosely mounted on the head 9 ofA a screw threaded bolt l0. Itis to be understood that a wedge and screw threaded bolt is provided for each 'expansion block, and that the said wedge 8 is located in each block or recess formed in the blocks 6'. Gne end of the bolt l() is Vprovided with a slot 11 in which a screw driver or other suitable tool may be inserted to 4force the wedge 8, up'- wardly in the slot 7, thus causing theblocks toiirmly press against the side and top of the casing, thus holding the casing in a position such as same would assume aswhen a pneumatic inner tube was used.

In order to prevent the flexible strips 4.- rom coming into contact with the inner $1.113-

I have inserted a covering of cloth or any other suitable material as indicated by the numerall l2, between' the flexible strips' and form of' myv invention wherein the iiexible strips i are heldV in positionl by Y' the casing l.

it is to be understood that openings are provided in the entire fastening meansQ/andv the elly 3 through Whichthe screw threaded.

- In. assembling my improved-'tire the screw threaded bolt carrying the Wedges 8 are positioned around the elly of. the Wheel, the flexible strips t heldA together` by means ot the covering- 12 are inserted 4in the,` casingl, after. Which the blocks 6 are positionedintheinner tube'fornied by the flexible. strips, and thercasing containing the inner tube` and blocks, said blocks being. spaced apart Within'the innerV tube are then placed around there ly of4 tliewheel, after which the casing andinnertube alongliviththe blocks 6 are moved longitudinally on the fellythus bringing thebloclrinto position to be expanded by thevfedges-S.v it is to beunderstoodthat as many screw threaded bolts and` Wedges can r'be used as is: desired or needed toiholditliek inner tube andY casing in expanded position` y From. practical exf periments: itghasv been found that six ex-` pansion blocks and six screw threaded bolts along with said Wedgesare sufficient to support the heaviest ofl-oads, and hold the casing. in an expanded position as same would assume in case the pneumatic inner tube was used.

In view of the foregoingdescription as to the construction Vand operationpf my invention, taken' in connection With the ac# compayingdrawing, it isthought that 'further explanation as to the constructionr and objects are unnecessary.V
